Figure l is a side elevation of the perforat- Fig. 2 is a plan of the same. Fig. 3 is an enlarged sectional side elevation on line y y, Fig. 4, of the perpendicular tube,

rod and needle, and actuating mechanism. Fig. 4 is an enlarged sectional front elevation of the same on line :v w, Fig. 3. Fig. 5 is an enlarged sectional elevation, showin g the joint of the device.

Similar letters of reference indicate corresponding parts.

Inthe drawings, A represents the standard, to the side of which is pivoted, nearits foot, a vertically-swim gin g arm, A', to thefrec end of which is secured an end of the chain B', that connects'it with the treadle B, and to which is also secured an end of the cord or chain C', that passes up over the segmental rocking sheave G2, which is pivoted in the standardbrace O3, and is secured in an end fastening or thimble,l a, whose open socket a' is tted over the wrist-pin b of the horizontal balance-wheel G, which is pivoted on the top of said standard A, so that by working the treadle B the wheel C is revolved.

On the opposite side of the standard A from the brace C3 are two laterally-projecting lugs, o, in and between which is pivoted by bolts or pins d, so that it may swing in a horizontal plane, the frame D, provided with two forwardextending horizontal parallel ears, f, setashort distance apart, one above the other, and in the extremities of the ears f is pivot/ed an upright T-Shaped spindle, E. A rocking-bar, F, provided with dependent end lugs, g, is pivoted on the horizontal head of said spindle E and parallel therewith by pins h, that are entered through said lugs g into the ends of said spindle-head E, so thatsaid bar F and its attachments have, when in operation, the rotary motion of the spindle E and the up-and-down rocking motion of the bar F. The spindle E i and bar Fconstitute the gilnbal-joint, connecting the horizontal arm G with the standard A.

Held on the top ot' this bar F and atright angles thereto by a clamp, F', is the swinging arm G, the rear end of which is connected. by

a spiral spring, 7L', with the lower ear,f,of the frame D, bythe tension of which spring h' said arm G and its attachments are moved in a ver- 'tical plane. To the outer end oi' thisarm G is rigidly attached a perpendicular tube, H,

surmouuted by and interiorly communicating with a cylindrical shell, I, which is fixed at the junction of said arm G andtube H. Through opposite sides of this cylinder l are introduced sharp-pointed screws l', between which is held the crank-shaft. K within said cylinder I. On thel wrist-pin of said crank-shaft K is secured the upper end ot a rod, L, that projects downward through the tube H, and has secured to its lower end bya pin, i, a stouter rod, M, whose lower end is screw-tapped, as shown at l, Fig. 3, and has screwed into it a short rod, N, in a longitudinal groove, m, in which a perforatingneedle, O, is soldered. This groove m is of sufiicientdepth to receive the whole diameter of the needle O, which is soldered and iitted in it, so that the rod N will move freely up and down in the bushing P.

Abushing, P, is screwed into thelower end of the tube H, and through this bushing P the rod M is extended, and is thereby prevented from moving out of a vertical plane.

A sheave, Q, is keyed on the crank-shaft K for receiving the belt or cord Q', that is also passed through the cylinder I and around the counter-sheave R.

Centrally and vertically on the arm G is iixed a yoke, S, through the top of which is screwed a set-screw, it, whose point serves as the top bearingof the spindle S', that has its lowerend pivoting in a .beariu g, o, on the top of the clamp F'. On this spindle S' are keyed in a horizontal plane the counter-sheave R and the smaller sheave R2. v

A belt or cord, T, connects the driving or balance wheel C with the sheave R2, so that when said driving-wheel C is putin motion the crank-shaftK is rapidlyrevolved, with the effeet4 of giving a quick up-and-down reciprocating motion to the rods L M N and needle O,

IOO

whereby, as the said needle O is passed over the surface of paper or other suitable material, the desired perforations are made.

A lug, p, extends laterally from the tube H, near the bottom thereof, and has passed up through it a screw-threaded bolt or guide, V, having a convex head, s. It is designed to adjust this guide V in, such a manner that its head s shall rest on the paper that is being perforated at a sufcient height above the point of the needle O to permit the latter to perforate to a sufticient depth.

The machine being set in motion, the operator takes hold of the guide V, and thus guides the needle O over the lines or patterns drawn upon the paper, so that a perforated pattern or design vis quickly formed.

It Will be observed that the needle O is held rigidly perpendicular,` so that none of the perforations produced by it are made in a slanting direction, and that the horizontal arm Gr and gimbal-jointE Fallow free horizontal and vertical motion to said needle O.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentl. The swinging arln G ond-bar F, connected at the rear by a spiral spring, h', with the frame D, and at the other end withtube H, in combination with a cylindrical shell, I, at thejuncy tion of said arm and tube, the screws I', and the crank-shaft K, carrying the rods L M N, with needle O, as shown and described.

2. The combination, with the swingingframev f D, carrying spindle E, of the rocking .bar F,
